COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Conduction System Pacing for Cardiac Resynchronization Therapy

open access: yesJournal of Cardiovascular Development and Disease, 2023
Cardiac resynchronization therapy (CRT) via biventricular pacing (BiVP-CRT) is considered a mainstay treatment for symptomatic heart failure patients with reduced ejection fraction and wide QRS. However, up to one-third of patients receiving BiVP-CRT are

Desmin variants: Trigger for cardiac arrhythmias?

open access: yesFrontiers in Cell and Developmental Biology, 2022
Desmin (DES) is a classical type III intermediate filament protein encoded by the DES gene. Desmin is abundantly expressed in cardiac, skeletal, and smooth muscle cells.

Development of the Cardiac Conduction System.

open access: yesCold Spring Harbor Perspectives in Biology, 2020
The cardiac conduction system initiates and propagates each heartbeat. Specialized conducting cells are a well-conserved phenomenon across vertebrate evolution, although mammalian and avian species harbor specific components unique to organisms with four-

Transcriptional Patterning of the Ventricular Cardiac Conduction System

open access: yesCirculation Research, 2020
Supplemental Digital Content is available in the text. Rationale: The heartbeat is organized by the cardiac conduction system (CCS), a specialized network of cardiomyocytes. Patterning of the CCS into atrial node versus ventricular conduction system (VCS)

Engineering a conduction-consistent cardiac patch with rGO/PLCL electrospun nanofibrous membranes and human iPSC-derived cardiomyocytes

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
The healthy human heart has special directional arrangement of cardiomyocytes and a unique electrical conduction system, which is critical for the maintenance of effective contractions.

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]

open access: yes, 2020
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

The Emerging Role of Cardiac Conduction System Pacing as a Treatment for Heart Failure

open access: yesCurrent Heart Failure Reports, 2020
Purpose of Review The aim of cardiac resynchronization therapy (CRT) is to improve cardiac function by delivering more physiological cardiac activation to patients with heart failure and conduction abnormalities.

Cardiac Reentry Modeled by Spatiotemporal Chaos in a Coupled Map Lattice [PDF]

open access: yes, 2022
Arrhythmias are potentially fatal disruptions to the normal heart rhythm, but their underlying dynamics is still poorly understood. Theoretical modeling is an important tool to fill this gap. Typical studies often employ detailed multidimensional conductance-based models.

Electrocardiographic patch devices and contemporary wireless cardiac monitoring. [PDF]

open access: yes, 2015
Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes.
